UNTED @fflfl HARRY ABRAMSON, OF PHILADELPHIA, PENNSYLVANIA.

GAS-HEATED IRON.

To all whom t may concern Be it known that I, HARRY ABRAMsoN, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Gas-Heated Iron, of which the following is a specification.

rlhis invention relates to gas heated sad irons and has for an object to provide an iron in which the ironing surface is evenly and uniformly heated at all points and wherein the heat distributing means are so arranged and constructed as to prevent localization of the heat at one or more points.

In gas irons, as heretofore constructed, it has been :found in practice that where the burner and its adjuncts are located at one end or the side of the iron body, it has been extremely difficult, if not impossible, to cause the flame to evenly distribute the heat over the bottom of the iron, and in fact such devices are more highly heated at the heel portion of the iron than at the toe. Itis very important that the toe of the iron should be heated to the same temperature as the heel of the iron, since it is the toe which first contacts with the damp articles and it is therefore subjected to an initial chilling so that it is preferable that the toe should be heated, if anything, to a higher temperature than the rest of the bottom of the iron.

It is an objectof my invention to overcome the foregoing defects and provide a burner mechanism which is so located with respect to the iron body, that the heat is distributed uniformly over the ironing surface and the flame is just as effective for heating one part, as another.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

The annexed drawings and the following description set forth in detail one mechanical form embodying the invention, such detail construction being but one of various mechanical forms in which the principle of the invention may be used.

Figure l represents a longitudinal, sectional elevation of a gas iron embodying my invention. Fig. 2 represents a lateral, sectional elevation thereof. Fig. 3 represents a sectional view on line w--zv Fig. l, on a reduced scale.

Specification of Letters Patent.

Application led February 24, 1913.

Patented Sept. 23, 1913.

Serial No. 750,135.

Similar numerals of reference indicate corresponding parts :in the figures.

Referring to the drawings :1 designates the body of the iron which is preferably hollow and substantially elliptical in form, so that the iron may be operated in either' direction, and thus reduce the chillingl effect on the toe of the iron in its initial contact with the damp articles being ironed.

2 designates a plurality of inlet openings distributed at suitable intervals adjacent the bottom 3 of the iron and serving as a means to introduce air into the body l, in order to complete the combustion of the gases and allow all the available heat to be abstracted therefrom.

The upper portion of the iron body 1., as here shown, is provided with longitudinal recesses 4l on the sides thereof, which serve as outlets for the products of combustion and prevent a gas cushion being formed in the body of the iron beneath the top plate 5.

(S, 7 and 8 designate a plurality of lugs infeferably formed integral with the bottom 3 and projecting a suitable distance within the hollow body to serve as heat retainers for distributing the heat uniformly over the bottom 3, and thereby maintaining the bottom evenly heated at all points, and it will further be noted that the lugs 7 preferably cover a suitable area, in order to conduct a suitable amount of heat to the toe end of the iron, where it is needed to overcome the aforesaid chilling effect.

The top plate 5, in the present instance, is detachably connected to the iron body l by providing at each end an open-ended slot 9 adapted to straddle a threaded pin 10, which screws into the threaded openings l1 provided at each end of the body l for the purpose. These pins l0 are each bent outwardly and downwardly in order to contact with the upper surface of the top plate 5 and securely clamp the same in its normal position upon the iron body 1. i

l2 designates the handle of the iron which, as here shown, is mounted on a suitable frame 13 and secured to the top plate 5 by means of screws 14 or other suitable fastening devices. The handle is preferably spaced from the plate 5 by lugs 35 and the boss 36 so that heat radiation is reduced.

In connection with the top plate 5, it will be noted that the same is provided with a transverse opening 15, disposed at substantially the center, and serving as a means to introduce the gas carrying conduits, which will now be described.

16 designates a suitable pipe fitting preferably tapering for frictional engagement with a washer 21, which seats, as here shown, on the boss 36. rThe fitting 16 terminates preferably in a threaded end 17 adapted for engagement with a suitable part of the tubular neck 18 of the burner 19, which neck, it will be noted, passes through a shield 20, see Fig. 1, and upwardly through the opening 15 into the boss 36, so that it is in proper position to be engaged by the said pipe fitung 1c. y

1n order to prevent turning movement of the burner 19which would cause relative displacement of the parts, l have preferably formed a pair of lugs 22 on the said neck 18, which are adapted to tity recesses formed in the boss of the opening 15, and in the sides of the opening of the shield 20, and the action should be readily apparent, as this forms a lock.

The 'burner 19 is formed of a casing having two chambers 23 and 24 formed by the plate 25, which is provided with the openings 26 situated adjacent the opposite ends of the burner, and forming communications between the chambers, the lower chamber being formed with lateral extensions intermediate the ends.

The tubular neck 18 of the burner is preferably situated at the center of the burner and communicates with substantially the center of the upper chamber 23, so that the gas enters the said upper chamber-23 and ows each way therein to the openings 26, andso enters the lower chamber 24 at each end thereof, thus insuring a full supply of gas which will be discharged through the Lperforations orV outlets 27 in the bottom plate of the burner, at the ends thereof, so that a full supply of heat will be positively imparted to the ends or toes of the iron, since it is the toe which first contacts with the damp articles. 1t will of course be understood that the gas will till the lower chamber 24, and will be discharged from all of the outlets 27.

28 designatesl projections forming nozzles 4around each outlet, which projections serve and which are situated a suitable distance v away from the wall of the body 1, whereby it will be understood that the asbestos lining or pad serves to hold in the heat, and the shield serves to deflect the heat downward in the iron, while the spaces between the members29 are of sufficient size and number to permit the escape of a suitable amount of the products of combustion through the recesses A4 of the body.

80 designates openings in the wall of the body 1 at each toe or end of the iron, said openings being suitably situated with respect to the burner 19, and shield 20, and to provide a sufficient amount of air to insure perfect combustion, and to so obtain the maximum amo-unt of heat from the ignited Gas.

a In the operation of the device, the gas enters the burner, after having passed through a suitable Bunsenregulator, and is delivered to the interior of the burner 19` and discharges through the openings in the bottom thereof. Here it is ignited and burns with the desired heat producing flame and substantially all the available heat is extracted by reason of the admission of air through the inlet openings.

It will now be apparent that I have devised a complete unitary structure, simple in construction, effect-ive in operation, and one in which substantially all the heat is extracted and taken up bythe bot-tom of the iron. It will further be noted that the provision of the shield 2O forms a heat chamber for dei'lecting any heat which would otherwise be lost, to the edges of the iron body,

and which materially assists in obtaining an of movement and will not continually be in the way of the user and obstruct the path of the iron during an ironing operation.

By my novel clamping means, connecting the burner and its adjuncts with the plate 5, it is possible, by simply giving the threaded pins 10 a partial turn, to remove the said plate and burner as a unit, thus making all the parts readily accessible for cleaning or repairs. Y

Other modes of applying the principle of my invention may be employed for the mode herein explained. Change may therefore be made as regardsKV the mechanism thus disclosed, provided the principles of construction set forth respectively in the following Claims are employed.
